Format number with currency & decimal to be part of a string

[stephenslaughter]

I am trying to figure out how to format a number (double) into currency and then add as part of a string.  Would this be a formula, regex, or is there an easy way to quickly convert a number to currency?

Program	Year	Cost	Output
Aaaa	2020	500.5	Aaaa (2020) $500.50
Bbbb	2020	600.6	Bbbb (2020) $600.60
Aaaa	2019	7000	Aaaa (2019) $7,000.00
Aaaa	2019	80	Aaaa (2019) $80.00
Bbbb	2019	9090.99	Bbbb (2019) $9,090.99

Just looked through the other solutions and it looks like no one accounted for commas. That makes it a little trickier. I put the formatting in a macro to make this a little cleaner:
